RESUMO
PURPOSE: Circumcision is one of the most frequently performed surgical procedures. Complications are infrequent, including bleeding, though can be significant such as shaft skin excision. The aim of this study was to identify mechanism of injury and reconstructive techniques for skin excision using a full thickness skin graft (FTSG) or with the novel application of tissue expanders (TE). METHODS: Patients who underwent penile reconstruction following shaft skin excision from an overzealous circumcision were retrospectively reviewed. The penis was covered using a FTSG, harvested from the groin/hip, or using TE, with expanders placed in residual shaft skin. RESULTS: Twelve patients experienced significant skin loss (range 65-95%) including 2 with partial glans loss. Ten were reconstructed using a FTSG and 2 with TE. Injury was most frequently from a Mogen clamp (n = 9), or from a Gomco clamp, Plastibell device, and electrocautery burns. Six FTSG patients experienced complications with lymphedema (n = 3) most common. CONCLUSION: Shaft skin excision is a devastating complication with risk greatest from Mogen clamp use. TE is preferred as this avoids donor site morbidity which reassures parents but requires sufficient residual skin that can be expanded. Both techniques effectively provide soft tissue coverage with acceptable appearance and long-term function.

PURPOSE: Male patients with exstrophy-epispadias complex have a congenitally short penis. Adolescent and adult patients often desire penile reconstruction to enable penetrative intercourse. When penile lengthening using local tissue and/or skin graft is unsuitable, phalloplasty is performed. We provide updated experiences using radial forearm free flap and pedicled anterolateral thigh flap phalloplasty techniques over a 6-year period in exstrophy-epispadias complex patients. MATERIALS AND METHODS: Consecutive patients who underwent radial forearm free flap or pedicled anterolateral thigh flap phalloplasty between 2013 and 2019 were reviewed. A total of 11 patients were identified, including 8 with classic bladder exstrophy and 3 with cloacal exstrophy. In each case, flap dimensions, donor and recipient vessels and nerves, complications, outcomes and subsequent surgical procedures are reported. RESULTS: A radial forearm free flap was performed in 6 patients and a pedicled anterolateral thigh flap in 5. Flap survival was observed in all cases and 5 patients subsequently received an inflatable penile prosthesis. Among patients undergoing a pedicled anterolateral thigh flap, there was 1 mortality from acute pulmonary embolism, and the other 4 required at least 1 debulking procedure. CONCLUSIONS: Phalloplasty is an important procedure in patients with exstrophy-epispadias complex with severe penile inadequacy. Both techniques have favorable long-term outcomes, although the pedicled anterolateral thigh flap frequently requires a later debulking procedure. The radial forearm free flap is preferred but if the radial forearm is overly thin and the risk of inflatable penile prosthesis extrusion is high, the pedicled anterolateral thigh flap is an acceptable alternative.

PURPOSE: We investigated surgical approaches to urinary incontinence and long-term continence outcomes after successful bladder reconstruction in a heterogeneous patient population with classic bladder exstrophy. We hypothesized that while most patients will achieve urinary continence after surgery, only a select group will void volitionally per urethra. MATERIALS AND METHODS: An institutional database of 1,323 patients with exstrophy-epispadias complex was reviewed for patients with classic bladder exstrophy who underwent successful bladder closure and a subsequent continence procedure between 1975 and 2017. Procedures included bladder neck reconstruction, bladder neck reconstruction with augmentation cystoplasty or continent catheterizable stoma, and bladder neck closure with continent catheterizable stoma. Cloacal exstrophy, epispadias and variant exstrophy cases were excluded from analysis. Continence at last followup was defined as a dry interval of 3 or more hours without nighttime leakage. Those patients with more than 3 months of followup were assessed. RESULTS: Overall 432 patients underwent successful bladder closure (primary 71.5%, repeat 28.5%) and a urinary continence procedure. At last followup 162 (37%) underwent bladder neck reconstruction, 76 (18%) underwent bladder neck reconstruction with augmentation cystoplasty or continent catheterizable stoma, 173 (40%) underwent bladder neck closure with continent catheterizable stoma and 18 underwent other procedures. Median followup from the first continence procedure was 7.2 years (IQR 2.3-13.7). Continence was assessed in 350 patients. After isolated bladder neck reconstruction 91 of 142 patients were continent (64%, 95% CI 56-72). After bladder neck closure with continent catheterizable stoma 124 of 133 patients evaluated were continent (93%, 95% CI 87-97). CONCLUSIONS: Most patients with classic bladder exstrophy require multiple reconstructive procedures to achieve continence. Only about 25% of patients are expected to void normally per urethra without reliance on catheterization or urinary diversion.

INTRODUCTION: The authors aim to compare single institutional 30-day complication rates between delayed and neonatal closure of classic bladder exstrophy (CBE). MATERIALS AND METHODS: An institutional database of 1415 exstrophy-epispadias patients was reviewed retrospectively for CBE patients who underwent primary closures at the authors' institution between 1990 and 2020. Patients were identified as having received either neonatal or delayed (at age >28 days) closures. All 30-day complications were recorded, including wound infection and dehiscence, genitourinary and non-genitourinary infections, bowel obstruction, blood transfusions, and others. Descriptive statistics were performed to summarize patient level data. Categorical variables were reported by count and percentages and were compared using Exact Cochran-Armitage trend analysis by decade, or with Fisher's Exact Test and Chi-square test when directly comparing categories and outcomes. Continuous variables were analyzed via Mann Whitney U and one-way ANOVA as appropriate. RESULTS: The cohort included 145 patients: 50 delayed and 95 neonatal closures. The total complication rate was 58% in delayed closures compared to 48.4% for neonatal closures (p = 0.298), with the majority being Clavien-Dindo grade I or II. Excluding blood transfusion, complication rates fell to 26% and 34.7% in delayed and neonatal closures, respectively (p = 0.349). The most common single complication was unplanned post-operative blood transfusion (38% delayed; 26.3% neonatal; p = 0.34), followed by pyelonephritis (2% delayed; 8.4% neonatal), and urinary fistula (6% delayed; 1.1% neonatal). Grade III Clavien-Dindo complications occurred in 2% delayed and 7.4% neonatal groups (n = 1; n = 7 respectively; p = 0.263). A single delayed patient had grade IV complications compared to three neonatal patients (p = 0.66). CONCLUSIONS: Delayed primary closure has become a frequently performed alternative in the modern treatment of bladder exstrophy for patients who do not undergo newborn closure because of prohibitive circumstances or surgeon's discretion. The majority of the complications associated with delayed closure are a low Clavien-Dindo grade and easily managed during the postoperative inpatient hospital stay. Families should be counseled about the possibility of minor, conservatively managed complications and likelihood of a blood transfusion with osteotomy.

OBJECTIVE: To investigate management trends in a single institution with a large referral population in classic bladder exstrophy (CBE) over the past twenty years. METHODS: An institutional database of 1415 exstrophy-epispadias complex patients was retrospectively reviewed for CBE patients with primary closure between 2000 and 2019. Osteotomy, location of closure, age of closure, and outcome of closures were reviewed. RESULTS: A total of 278 primary closures were identified, with 100 occurring at author's hospital (AH) and 178 at outside hospitals (OSH). Osteotomies were performed in 54% of cases at AH and 52.8% of cases at OSH. Osteotomy use increased over 20 years from 48.6% in 00's to 62.1% in 10's (Pâ¯=â¯.046). The total success rate at AH was 96% and 62.9% at OSH. The median age at primary closure at AH increased from 5 days (00's) to 20 days (10's), compared to the OSH which increased from 2 days (00's) to 3 days (10's). CONCLUSION: Closure of CBE may be delayed for several reasons including insurance difficulties, transfer to another hospital, desire for second opinions, or surgeon preference. Delaying primary closure of bladder exstrophy gives families time to adjust lifestyle, arrange travel, and seek care at centers of excellence.

INTRODUCTION AND OBJECTIVE: The bladder exstrophy-epispadias complex (BEEC) is a rare spectrum of congenital genitourinary malformations with an incidence of 1:10,000 to 1:50,000. Advances in reconstructive surgical techniques have improved clinical outcomes, but there is a paucity in data about disease sequela in adulthood. This is the largest survey to date in the United States exploring the urinary continence, bladder management, and oncologic outcomes in adults with BEEC. METHODS: Respondents were over the age of 18 with a diagnosis of bladder exstrophy, cloacal exstrophy, or epispadias. They were treated at the authors' institution, included in the Association for the Bladder Exstrophy Community (A-BE-C) mailing list, and/or engaged in A-BE-C social media. A survey was created using uniquely designed questions and questionnaires. Survey responses between May 2020 and July 2020 were processed using Research Electronic Data Capture (REDCap). Quantitative and qualitative statistics were used to analyze the data with significance at p < 0.05. RESULTS: A total of 165 patients completed the survey. The median age was 31.5 years (IQR 25.9-45.9). Many patients considered themselves continent of urine, with a median satisfaction score of 74 (IQR 50-97) on a scale from 0 (consider themselves to be completely incontinent) to 100 (consider themselves to be completely continent). There was less leakage among those with a continent urinary diversion compared to those who void or catheterize per urethra (p = 0.003). Patients with intestinal-urinary tract reconstruction, such as augmentation cystoplasty or neobladder creation, were more likely to perform bladder irrigations (p = 0.03). Patients with continent channels were more likely to report UTI than all other forms of bladder management (89.0% vs. 66.2%, p = 0.003). Three (1.9%) patients were diagnosed with bladder cancer. A small portion of patients (27.2%) were given bladder cancer surveillance recommendations by a physician. DISCUSSION: Most patients achieved a satisfactory level of urinary continence, with the highest continence rates in those with a continent urinary diversion. Those with intestinal-urinary tract reconstruction were more likely to perform bladder irrigations, perhaps to avoid complications from intestinal mucous production. The rates of self-reported UTI and were higher in patients with continent channels, but recurrent UTIs were not affected by the type of genitourinary reconstruction. Bladder cancer exists in this population, highlighting the need for long-term follow-up. CONCLUSION: Most BEEC patients achieve a satisfactory level of urinary continence, with the best outcomes in those with a continent urinary diversion. This population requires long-term follow-up with a transitional urologist to ensure adequate oncologic care.

BACKGROUND: Following successful closure of patients with classic bladder exstrophy (CBE), the next major milestone is the establishment of urinary continence. Prior to determining the most appropriate continence surgery, it is imperative to reach an adequate bladder capacity minimum of 100 cc in order to make the decision between bladder neck reconstruction (BNR) or continent stoma, with or without augmentation cystoplasty (AC). OBJECTIVE: To examine the timing of when patients achieve threshold bladder capacity for BNR eligibility. We hypothesize most patients will achieve an adequate bladder capacity (100 cc) by 7 years old when continence surgeries will begin to be considered. STUDY DESIGN: An institutional database of 1388 exstrophy patients was retrospectively reviewed for CBE patients after successful primary bladder closure. Bladder capacities were measured via gravity cystography and data presented as descriptive statistics. The cohort was stratified by location, neonatal (≤28 days) or delayed closure period and osteotomy status. The bladder capacities were categorized to either reaching goal or not and a cumulative event analysis was performed. The event being reaching 100 cc capacity or greater and time being the number of years between bladder closure and attainment of goal capacity. RESULTS: 253 patients met inclusion criteria between 1982 and 2019. The majority were of male gender (72.9%), had their closure performed at the authors' institution (52.5%), within the neonatal period (80.7%), and without an osteotomy (51.7%). 64.9% of patients reached goal bladder capacity. There were no significant differences in those who did or did not achieve goal except for clinical follow up. Cumulative event analysis demonstrated a median time of 5.73 years (95% CI 5.2-6.20) corresponded with a 50% event probability of reaching goal capacity. Cox-proportional hazards showed location of closure was significantly associated with hazards of reaching goal bladder capacity (HR = 0.58, CI 0.40-0.85, p = 0.005). Based on this model, the median time to event would be 5.20 years (95% CI 4.76-5.80) for cases done at the authors' hospital and 6.26 years for those performed at an outside hospital (95% CI 5.77-7.24). CONCLUSIONS: These findings help surgeons counsel families appropriately on the odds of attaining goal capacity at various ages. For those who do not reach 100 cc by five years of age, it helps further characterize the odds of requiring a continent stoma with bladder augmentation and the best timing for reconstructive surgery in order to safely gain urinary continence. Families may also be assured that most patients would have the breadth of surgical options when it comes to continence as more than half of patients reached the bladder capacity threshold.

Background: Higher temperatures have been associated with increased stone formation and subsequent utilization of hospital resources, including inpatient admission. However, these observations have been derived from the adult population. We sought to examine if this purported association extends to the pediatric population. Methods: We used the 2016 Kids' Inpatient Database to identify nationwide pediatric inpatient admissions related to nephrolithiasis. Temperature data from the National Oceanic and Atmospheric Administration was linked to each admission. Comparative statistics analyzed patient and admission characteristics. Multivariable logistic regression analyzed associations between stone-related admissions and temperature. As a frame of reference, this analysis was replicated using the National Inpatient Sample from 2016 to evaluate associations in the adult population. Results: Of the 2,496,257 pediatric admissions, 8453 (0.33%) were related to nephrolithiasis. Temperatures at the time of stone admission were higher than those during nonstone admission (55.9°F vs 54.8°F, p < 0.001). The stone admission group had a higher proportion of females than the nonstone admission group (64.8% vs 55.4%, p < 0.001). Stone admission was significantly associated with temperature (odds ratio [OR] 1.025 per 10°F, confidence interval [95% CI] 1.003-1.049, p = 0.03) and female gender (OR 1.097, 95% CI 1.027-1.171, p = 0.006). In the adult population, 380,520 out of 30,000,941 patients (1.3%) were admitted with a stone. The effect of temperature on stone admissions was similar to that in the pediatric population (OR 1.020, 95% CI 1.014-1.026, p < 0.001), but women were >20% less likely to be admitted for stones than men (OR 0.770, 95% CI 0.757-0.784, p < 0.001). Conclusions: Increased temperatures were associated with an increased risk of stone-related admission in both the pediatric and adult populations. Females were at increased risk for stone-related admissions during childhood, but this trend reverses in adulthood.

INTRODUCTION: The penis in exstrophy-epispadias complex (EEC) males is diminutive and patients are often dissatisfied with appearance and length. Due to an increased risk of psychosexual dysfunction, patients desire penile reconstruction. Surgical options include penile lengthening with a full thickness skin graft (SG) or tissue expansion (TE) used for cutaneous coverage or neophalloplasty using a radial forearm free flap or pedicled antero-lateral thigh flap. OBJECTIVE: The aim of this study was to assess sexual health outcomes before and after SG or TE assisted lengthening and neophalloplasty. STUDY DESIGN: Patients aged 18 years or older, who underwent penile reconstruction were identified using an institutionally approved database of EEC patients. Patient perception of penile appearance, sexual function, their frequency of sexual intercourse and overall satisfaction with reconstruction were assessed using a survey consisting of validated and non-validated questions. RESULTS: Eighty-three patients underwent penile reconstruction, 57 met the inclusion criteria and 28 responded to the survey (49.1%). Fourteen were reconstructed using a SG, 6 with TE and 8 underwent neophalloplasty. Median time from reconstruction to survey completion was 4.4 years (range 1.2-13.2) Four patients had a diagnosis of epispadias, 1 cloacal exstrophy, 23 classic bladder exstrophy (CBE). Before reconstruction patients were dissatisfied with their penile appearance with a median penile perception score of 4.5 compared to 7.5 after surgery (p = 0.0034, Fig. 1). Twenty-three patients were dissatisfied with penile length, with 18 reporting an improvement following reconstruction (p = 0.0002). There was no correlation in time after reconstruction with PPS or satisfaction with penile length (p = 0.86 and p = 0.55, respectively). Overall, the median Sexual Health Inventory for Men (SHIM) score was 19, with no difference between the surgical groups (p = 0.33). Nine patients engaged in sexual intercourse before reconstruction which increased to 17 afterwards. CONCLUSION: All three surgical methods improved patient perception of penile appearance and length. Patients who previously never engaged in intercourse were able to and those who had were doing so more frequently, of which a greater proportion were in a relationship. The results are encouraging though must be interpreted with caution due to the small number of responders and possible risk of bias. These findings provide vital information for future patients and routine psychological assessment will help manage patient expectations to improve satisfaction.

INTRODUCTION: Pelvic osteotomy is indicated in classic bladder exstrophy (CBE) patients with a wide pubic diastasis or non-malleable pelvis. While the safety of pelvic osteotomy in delayed and failed closures is established, there remains less clarity on their safety in newborns. The authors herein sought to present their experience with CBE patients who underwent pelvic osteotomy for assistance with bladder closure during both the newborn and delayed time periods. OBJECTIVE: The authors hypothesize that pelvic osteotomy during exstrophy closure may be performed safely in newborns with few perioperative or post-operative negative sequelae. STUDY DESIGN: A prospectively maintained IRB-approved database was reviewed for CBE patients who underwent osteotomy during primary closure. Patient demographics, performing institution (authors' or outside), closure outcome, diastasis width, and post-operative complications were noted. Patient subgroups included newborn and delayed (>28 days of life) closures. Failure was defined as bladder dehiscence, prolapse, outlet obstruction, or vesicocutaneous fistula requiring reoperation. Orthopedic complications included nerve palsies, superficial pin-site infection, and bladder neck erosion by orthopedic hardware. Analyses were performed using a Chi-square test. RESULTS: 286 patients were included: 186 newborn and 100 delayed closures. The authors' institution performed 109 cases (44 newborn and 65 delayed). Within the overall newborn closure cohort, no significant differences were found in outcomes among the osteotomy types with success rates of 80%, 60.8%, and 71.4% in the combined, posterior iliac, and anterior innominate groups, respectively (p = 0.24). In the delayed group, success rates were significantly different with rates of 100%, 72.4%, and 93.8% in the combined, posterior iliac, and anterior innominate groups, respectively (p < 0.001). Febrile urinary tract infection (UTI) was the most common complication at 8% (23/286). Only 1.7% (5/286) of patients had orthopedic complications with 3 patients in the newborn cohort, 2 patients in the delayed cohort, and only one patient requiring reoperation. DISCUSSION: Orthopedic complications are rare in CBE patients who undergo osteotomies regardless of the closure period. No clinically significant difference in orthopedic complication rate was found between newborn and delayed closure periods. CONCLUSIONS: While current trends have moved toward delayed primary closures, there remains a role for osteotomy during exstrophy closure in select newborn patients and can be performed safely with few complications.

INTRODUCTION: Several surgical methods have been used for primary repair of bladder exstrophy in the newborn. Complete primary repair of exstrophy (CPRE) aims to prevent the need for surgeries beyond the newborn period. Due to the rarity of bladder exstrophy, it has proven difficult in the past to analyze whether use of this method of closure truly does confer acceptable continence outcomes and hence minimizes the requirement for additional surgeries later in life. OBJECTIVE: To describe the continence outcomes of CPRE patients who went on to receive bladder neck reconstruction (BNR), and secondarily, to compare clinical features between those patients who were able to receive undergo a BNR compared to those who were not. STUDY DESIGN: An IRB approved database of 1330 exstrophy-epispadias patients was used to identify referred patients after successful CPRE for management of continued urinary incontinence. Urinary continence outcomes were assessed in those who underwent modified Young Dees Leadbetter BNR following CPRE. RESULTS: Sixty-one patients were referred for treatment after successful CPRE between 1996 and 2016. None developed continence or a dry interval after primary closure. Of these, forty-two (68.9%) underwent BNR by a single surgeon at a mean age of 5.8 years (range 5-8.4). The mean bladder capacity at BNR was 147 mL (range 102-210 mL). Twenty-five (59.5%) achieved day and night continence, 7 (16.7%) gained daytime continence with nocturnal leakage, and 10 (23.8%) remain totally incontinent. Mean follow-up after BNR was 5.9 years. Combined CPRE and pelvic osteotomy were performed in 100% of patients who were continent and 75% of those who were daytime dry. No continent patient had a ureteral reimplantation before BNR, whereas 4 patients with daytime continence and nocturnal leakage and 7 patients who remained continuously incontinent did. DISCUSSION: This is the largest known series of BNRs in exstrophy patients closed by CPRE. Previous smaller studies have demonstrated mild to moderate success rates of BNR after CPRE, with many patients still requiring additional continence surgeries. The present study found similar results, with additional indication that successful primary closure and use of pelvic osteotomies may correlate with enhanced continence. This study includes outcomes from a single surgeon, with a maximum length of follow up of 13 years. CONCLUSIONS: CPRE alone often does not render patients continent of urine, based on the authors' referral population. However, following BNR continence rates in this subgroup were found to reach 76%. Surgeons who treat this population should keep these factors in mind when planning continence surgeries.

INTRODUCTION: With current trends towards delaying the closure of classic bladder exstrophy (CBE), bladder growth rate or ultimate capacity may be impacted. OBJECTIVE: To examine consecutive bladder capacities in CBE patients who had primary closures at differing ages and determine whether there is an optimal age for closure, with reference to bladder capacity. STUDY DESIGN: A retrospective review was performed using an institutional database. INCLUSION CRITERIA: CBE, successful neonatal (i.e. ≤28 days old) or delayed (i.e. >28 days old) primary closure, at least three consecutive bladder capacities or two measures taken 18 months apart, and first bladder capacity measured ≥3 months after closure. Only capacities prior to continence surgery and before 14 years of age were considered. Two cohorts were created: neonatal and delayed closure. To account for repeated measurements per patient, a linear mixed model evaluated effects of age and length of delay on bladder capacity based on closure cohort. Individuals in the delayed closure group were further stratified into quartiles to assess for detriment to the bladder based on length of delay. RESULTS: The cohort included 128 neonatal and 38 delayed patients. Median age at closure for the delayed group was 193 days (IQR 128-299). Based on univariate analysis, for the first three capacity measurements, the delayed group had significantly lower capacities despite having a similar median age when the measurements were taken. Linear mixed effects model showed significantly decreased total bladder capacity in delayed closure compared to neonates. The 2nd and 4th quartile groups had the most significant decreases in capacity. DISCUSSION: Time points for the most significant decline appear after the 2nd and 4th quartiles, representing 4-6 months and beyond 9 months, respectively. From this, the authors theorize that the appropriate time to close an exstrophy patient is as early as possible (1st quartile), or, if a delay is needed for growth of a bladder template, then between 6 and 9 months (3rd quartile). There may be a detriment to growth rate, however, statistical power may be lacking to discern this. Study limitations include the single-centered, retrospective design. However, results described here fill an important deficit in the knowledge of managing CBE. CONCLUSIONS: All patients in the delayed bladder closure group demonstrated a decline in bladder capacity compared to the control neonatal closure group, with significant differences in the 2nd and 4th quartiles. Thus, closing the bladder prior to nine months of age is recommended.

BACKGROUND: Men born on the bladder exstrophy-epispadias complex (BEEC) spectrum may undergo neophallus reconstruction with a variety of free flaps, most commonly radial forearm. In order to achieve erectile function, a penile prosthesis may be inserted following neophallus construction. OBJECTIVE: In this study, we sought to describe the perioperative and clinical outcomes of inflatable penile prosthesis (IPP) insertion into neophalluses of patients along the BEEC spectrum. STUDY DESIGN: Using a prospectively maintained institutional BEEC database, patients who had undergone both neophallus creation and IPP placement were identified for this study. Surgery was performed by two surgeons with expertise in IPP implantation. Operative details and postoperative outcomes and complications were collected with review of the medical record. RESULTS: Overall, there were a total of 13 men who underwent neophallus reconstruction with subsequent IPP placement. Of these men, 76.9% (10/13) had experienced successful primary closure in childhood. One patient had corporal loss secondary to complete primary repair of exstrophy (CPRE) following a failed primary attempt. The average age at IPP placement was 23.2 years (SD ± 5.06). Mean OR time (n = 11) was 244.8 min (SD ± 46.2). 76.9% (10/13) of the cases used AlloDerm™ as a neotunica albuginea for support of the IPP. Three patients (23.1%) experienced complications all of which required revision surgery. Two of these complications were erosions in patients for whom AlloDerm™ was not used in the initial IPP placement. DISCUSSION: The results of this study suggest that IPP placement in neophalluses of males on the BEEC spectrum have low perioperative and postoperative morbidity with successful outcomes. While the rate of complications is notably higher in this group compared to the native penis IPP literature, the use of AlloDerm™ or other allograft materials may help to narrow this gap. CONCLUSIONS: IPP placement in neophalluses of men on the BEEC spectrum is successful in the majority of cases. Complications may be reduced with the use of AlloDerm™ in initial placement.

Posterior urethral valves (PUVs) present clinically across a varied spectrum, ranging from severe obstruction with massive distension of the bladder and upper urinary tracts in the fetus, to a much more indolent course with minor secondary changes in the young or older child. Type III (diaphragm) PUVs are relatively uncommon, and are associated with difficulty in passing a transurethral catheter into the bladder as well as smooth dilation of the bladder. The following case examines the unusual experiences of both diagnosing PUVs in a teenager, and capturing visual evidence of type III valves during cystourethroscopy.

INTRODUCTION: After unsuccessful repair of bladder exstrophy, when to repeat surgical intervention is unclear. One must balance time required for tissue healing with the damaging effects of an exposed urothelium to the environment. OBJECTIVE: The authors aim to study whether a relationship exists between bladder growth/capacity and time till eventual successful closure. STUDY DESIGN: An institutional database of exstrophy-epispadias complex patients was queried for failed exstrophy closure with successful repeat reconstruction, at least three consecutive bladder capacity measurements, and measurements obtained at least three months following successful closure. Patients closed successfully in the neonatal period were used as a comparative group. Linear mixed effects models were used to study the effect of time and age on bladder capacity. RESULTS: Forty-seven patients requiring reclosure and 117 who had successful neonatal closures were included. Two models were created. The first linear mixed effects model found that for a given age, the bladder capacity declined approximately 9.6 mL per year (p = 0.016). The second model found that when time to successful closure was grouped by quartiles, compared to neonates, those in the fourth quartile had significantly decreased bladder capacity of 28.8 cc (p = 0.042). An interaction model comparing neonates and those requiring reclosure did not demonstrate a significant change in bladder growth rate (p = 0.098). A model stratified by quartiles similarly did not find any significant impact to bladder growth rate. DISCUSSION: From the general linear mixed effects models, the authors conclude when compared to neonates, (1) there was an approximate 9.6 cc loss of total bladder capacity per year taken until successful closure, and that (2) those who were delayed the longest had the most significant difference in bladder capacity. This study required stricter inclusion criteria compared to previous publications, and therefore the conclusions that can be drawn regarding bladder growth rates may be more reliable. Future studies will examine the effects of delayed closure on the bladder at the cellular level. CONCLUSIONS: There is a demonstrable significant impact on overall bladder capacity with increasing delay to successful reclosure. One should be cautious when prolonging reconstruction of the bladder as these data demonstrate a time dependent decline in overall capacity.

INTRODUCTION: While evaluation and management options for classic bladder exstrophy (CBE) patients are numerous and varied, little is known regarding the relative utilization of these different methods throughout the world. A large group of exstrophy surgeons practicing globally was surveyed, seeking to document their methods of care. METHODS: A list of international exstrophy surgeons' email addresses was compiled using professional contacts and referral networking. An online survey was sent to each email address. Surgeons who had not performed a CBE closure within the previous 5 years were excluded. Survey questions queried the respondents' surgical practice type, years since training, and their preferred methods of preoperative evaluation, operative management, and postoperative management. Survey invitations were sent out starting in December 2014 and responses were collected for approximately 6 months. RESULTS: A total of 1152 valid email addresses were invited, resulting in 293 respondents (25%) from 39 countries and every American Urological Association (AUA) section. Seventy-six were excluded, leaving 217 respondents (Table). Respondents reported a median of 17 years since finishing their surgical training (IQR 8-25 years). Practice types included pediatric urology (n = 209), general urology (n = 9), pediatric surgery (n = 59), and other practice makeup (n = 3). On subgroup analyses, there were no significant regional practice differences, with the exception of complete primary repair of exstrophy (CPRE) and oral opioid prescribing being significantly higher in North America compared to other regions. DISCUSSION: Findings indicate that there may be diversity in CBE practice patterns globally. While most responding surgeons from regions outside of North America indicated modern staged repair of exstrophy (MSRE) as their preferred closure technique, a relatively equal distribution of respondents from North America selected CPRE and MSRE. A majority of North American surgeons chose performing osteotomies for both newborn and delayed closures, while an appreciable number of respondents from other regions selected never using osteotomies in their closures. Limitations to this study include a low survey response rate, particularly from surgeons outside of the United States, which may have significantly impacted the ability to draw meaningful global comparisons. CONCLUSIONS: Global variation among practices of surgeons performing CBE closures may exist. The wide range of methods demonstrated by this survey suggests the need for more conclusive comparative studies to elucidate whether an optimal standard exists. Local social factors, access to surgical expertise and transportation to referral centers, and finances play a role in what constitutes the best operative approach.

INTRODUCTION: Repair of classic bladder exstrophy (CBE) is known to alter dimensions of the bony pelvic ring. Pelvic volume and acetabular configuration are additional metrics which merit analysis in the reconstruction process. Advances in magnetic resonance imaging (MRI) allow for precise elucidation of such anatomy in pediatric patients, providing enhanced knowledge of how primary reconstruction may impact factors in pelvic health. METHODS: An IRB-approved exstrophy-epispadias database of 1337 patients was reviewed for patients with CBE who had pelvic MRI performed before and after repair. Pelvic MRIs were analyzed by a pediatric radiologist, and three-dimensional volumetric renderings of the true pelvis were calculated. Pre- and post-closure imaging were compared, in addition to imaging from age-matched controls without pelvic pathology. Cartilaginous acetabular index and version angles were also calculated and compared between groups. RESULTS: Eighteen patients with post-closure imaging, 14 of whom also had pre-closure imaging, and 23 control patients (ages 0-365 days) were included. The median ages at pre- and post-closure scan were 2 and 178 days, respectively. Osteotomy was performed in 6 (33%) of the closures. The median segmented pelvic volumes were 89 cm3 in the pre-closure group, 105 cm3 in the post-closure group, and 72 cm3 in the control group. At a given age, patients with CBE pre-closure had the largest pelvic volume, and those without bladder exstrophy demonstrated the smallest pelvic volumes (Summary Figure). CBE patients' pelvic volumes were overall lower following repair, relative to age (p = 0.007). Cartilaginous acetabular version angle increased following closure, with acetabular orientation converting from retroversion to anteversion in all cases. However, only acetabular version angles were significantly different between groups. DISCUSSION: This study found that pelvic volume significantly decreased relative to age following primary repair of CBE, but that it did not correct to control levels. Similarly, acetabular retroversion that is naturally seen in exstrophy patients was converted to anteversion post-closure but did not become completely normal. Knowledge of these persistent anatomical anomalies may be useful in treatment of future concerns related to exstrophy, such as continence achievement, pelvic organ prolapse, and potential gait disturbances. Lack of significant differences between study groups regarding acetabular index angles can give assurance to providers that hip dysplasia is neither a natural concern nor iatrogenically inflicted through reconstruction. CONCLUSIONS: The primary closure of exstrophy results in pelvic volumes and anteverted acetabula that more closely resemble those without bladder exstrophy, compared to pre-closure findings.
